If you are not willing/able to be online 24 hours prior to your flight to check in, I would buy EBCI otherwise, I would not. I would plan on 2 hours in airport, plan accordingly to park, drop off rental car, etc. Have your ids accessible. Pack liquids properly. Either pack something to eat on board or get something portable at the airport, depending on length of flight & times. You can bring liquids like water or soda on board so long as you buy after the security checkpoint. SW serves beverages in the air, alcoholic have an additional charge. SW's magazine usually has some interesting articles. Have fun!
